Abstract

A method and a system for operating bits of memory cells in a memory array, the method including applying a first operating pulse to a terminal of a first cell, the first operating pulse is intended to place the first cell into a predefined state; and applying a second operating pulse to a terminal of a second cell in the set, the second operating pulse is intended to place the second cell to the predefined state, and the pulse characteristics of the second operating pulse are a function of the response of the first cell to the first operating pulse.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A method of operating a set of memory cells in a memory array, the method comprising:
 applying a first operating pulse to a terminal of a first cell, wherein the first operating pulse is intended to place the first cell into a predefined state; and 
 applying a second operating pulse to a terminal of a second cell, 
 wherein the second operating pulse is intended to place the second cell to the predefined state, and 
 wherein the pulse characteristics of the second operating pulse are a function of the response of the first cell to the first operating pulse. 
 
     
     
       2. The method according to  claim 1 , further comprising a step of applying a third operating pulse to a terminal of a third cell,
 wherein the third operating pulse is intended to place the third cell to said predefined state, and 
 wherein the pulse characteristics of the third pulse are a function of the response of the first and the second cells to the first and the second operating pulses, respectively. 
 
     
     
       3. The method according to  claim 1 , wherein said pulse characteristics of the second operating pulse are adjusted by adjusting the duration of the second operation pulse. 
     
     
       4. The method according to  claim 1 , wherein said pulse characteristics of the second operation pulse are adjusted by adjusting the amplitude of said second operation pulse.
